Just an update for all you guys out there that have been trying to help me! Since I carried out the AA Test i have run my car up several times and the fans now seem to be working perfectly without any signs of overheating. Not sure whether the test has reset something or kickstarted them into working but all is good in the hood! Maybe everything needed resetting as it sat for a few months and i had to put on a new battery? Anyway, thanks ever so much to everyone and I will keep you all posted... (Things dont normally work out this easy for me so no doubt i will be back soon with more questions)😆xxx

Am i right in thinking that the ECU controls the fans but the ECU has to get its signal from the temp sender first? Having looked into the AA test, I also believe that the check is purely electrical and just proves that all of the fuses are working to the electrical components in the test? I still cant understand why the fans work perfectly well under test but will not work when the car is running.......Think im gonna change the temp sender first (well not me personally) just as a process of elimination. Its worth starting small and working up to big bucks!!!! Is this a good idea or am I being totally female.......? Julie.x

Im sooo grateful for all of your input... Yes, the temperature gauge went sky high into the red.....

Forgot to ask ZMANALEX, do you supply the motors on their own or with fans? Thanks ever so....

Thanks for the info but can anyone tell me why they work perfectly when i perform the AA Test?😕

Hi, Im new to this so please bear with me. I have a 53plate 350z that is my pride and joy. Seeing as the sun was shining at the weekend I decided to get my 'zed' out from under its cover where its been hiding all winter and get him prepped for the summer. Took it up the road to clean the brakes, got back home and it overheated on me on the driveway. We bled the system to get rid of any airlocks but it appeared that neither of the rad fans were cutting in. I took it to my local garage yesterday and it seems that they cannot turn the fans on independently via their computer, however, they will work if tapped with a small hammer, albeit slow and only for around 20 secs. They think that I need new fans at a cost of just under 1k....As you can imagine, im absolutely gutted! I picked the zed up this arvo, a relatively short journey home so no chance of overheating and have since spent all my time surfing the net and 'googling'. I then came across the Auto Active Test and even though im a woman, it seemed relatively easy to carry out so decided to give it a go. Much to my amazement the fans kicked in perfectly and were spinning like they should.....!? Now im stuck, does anyone have any ideas whats happening and where I should be going next? Temp sender maybe? As previously mentioned, I am female but can find my way around some of this stuff if given the right help..... Thank you Julie.x
